Requirement is:

Hi @XYD23 ,

 Create onChange - client script on Priority field:

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    if (newValue != oldValue && newValue == 1) {
        g_form.setValue('description', 'this is a critical incident');
    }

}

Hi @XYD23 ,
As per your requirment using both SI and CS
Try this:
Client Script

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '') {
        return;
    }

    if (newValue == 1) { // Assuming '1' is the value for Critical priority
        var gr = new GlideAjax('UpdateIncidentPriority');
        gr.addParam('sysparm_name', 'updateDescription');
        gr.getXML(onComplete);

function onComplete(response) {
            var answer = response.responseXML.documentElement.getAttribute("answer");
            var result = JSON.parse(answer);
			g_form.setValue('description',result.desc);
        }
    }

}

Script Include: (Name - UpdateIncidentPriority, Make it client callable)

var UpdateIncidentPriority = Class.create();
UpdateIncidentPriority.prototype = Object.extendsObject(AbstractAjaxProcessor, {
    updateDescription: function() {
        var obj = {};
		obj.desc= "This is critical Incident";
		return JSON.stringify(obj);

    },
    type: 'UpdateIncidentPriority'
});

 Please replace '1' with the actual value for Critical priority in your ServiceNow instance.

You don't need to make GlideAjax call for this as the requirement can handle using client script only

You can write an onChange client script on priority field as mention below code:

if(newValue == 1){
 g_form.setValue('description',"This is a critical incident")
}else{
  g_form.clearValue("description");
}
